Circulating Tools

Upper-well cleanup tools

This suite of tools is run as part of the main wellbore cleanup, as well as on upper well cleanup runs. Our circulating tools provide alternative flow paths to permit faster flow rates at critical points in the well. Pressure relief is realized when the tools are opened, boosting fluid flow that circulates debris and swarf out of the wellbore.

We provide tools for use in drilling applications and weight-set (multifunction circulating tool) units specifically for wellbore cleanup operations. Our offerings also include ball-drop valves with sliding sleeves that open and close the circulating ports.
